|

# Returns a single property of a given country. Available properties are:

|
#
|
|
# name Name of the country as read from _PATH_ISO3166.
|
|
# nzones Number of zones within the country (-1 if country has
|
|
# only a single zone).
|
|
# filename The filename portion of the TZ field (after the `/') as
|
|
# read from _PATH_ZONETAB.
|
|
# cont The principal continent in which the country lies (appears
|
|
# before the `/' in the TZ field of _PATH_ZONETAB).
|
|
# filename_N Like filename, but for the Nth zone when the country has
|
|
# multiple zones (nzones > 0).
|
|
# cont_N Like cont, but for the Nth zone when the country has
|
|
# multiple zones (nzones > 0).
|
|
# descr_N Like name, but for the Nth zone when the country has
|
|
# multiple zones (nzones > 0)
|
|
#
|
|
# If $var_to_set is missing or NULL, the value of $var_to_get is printed to
|
|
# standard output for capturing in a sub-shell (which is less-recommended
|
|
# because of performance degredation; for example, when called in a loop).
